SKP15.013U2 Siemens Actuator

Overview

The Siemens SKP15.013U2 is a high-performance electro-hydraulic safety shut-off actuator designed for use with Siemens VG series gas valves. It serves as a critical safety component in industrial and commercial burner systems by providing reliable ON/OFF control. Engineered for high-demand applications, this actuator opens slowly to ensure a stable burner light-off and closes rapidly (in less than 0.8 seconds) upon power interruption to ensure fail-safe operation. This specific U2 model is the North American 220-240 VAC variant and is configured without auxiliary or proof-of-closure switches.

Features

• Self-contained electro-hydraulic mechanism with an internal oscillating pump
• Fail-safe design with rapid spring-return closure on power loss
• Damped/slow opening characteristic for controlled burner ignition
• Integrated visual stroke position indicator for easy monitoring
• “Power on” indication light visible through the terminal cover
• Tool-less, modular mounting allows for 360-degree rotation in 90-degree steps
• Low power consumption for efficient continuous operation
• Rugged housing compatible with harsh industrial environments
